As someone who has put a signigicant amount of mods into several cars and then sold them... Don't expect to get anywhere near what you put into it. You mod cars and do the work because you love them, not to make the money. A modded car, no matter how cool is only worth marginally more than an un-modded one, sometimes less. Even engine swaps aren't that big of a deal anymore. Most people would rather buy a stock car and do the work themselves, so buying somebody else's baby isn't of much use.

Also - selling an unfinished project (ie no paint) is worth way less... Putting a paint job on the car will get you more money in the long run than the paint job cost.

Basically the reason people part out cars with mods is to make back some of the money... Your car isn't to my personal taste, but maybe someone likes it and will be willing to pay it. Even with all the mods I'd say its worth about 3k, maybe 4k with an awesome (not Maaco) paintjob. Good luck with the sale.
